FRANK KING, OF FOUNTAIN, COLORADO;

. ANTISKIDDING DEVICE.

To all iohom may concern: 1

Be it known that.I,,FR-ANKK1NG, a citi' zen of the United States,residing at Fou-n-j tam, in. the county of El Pasoand State of Colorado,have invented certain new and useful Improvementsgi-n AntiskidditlgDevices, of which the following is aspecification.

This invention relates to anti-skidding devices and is especiallyadapted for connection with automobile wheels.

More specifically, it is the object of this invention to provide aplurality of spurs or ground engaging elements in connection with eachwheel, the same beingnormally positioned in an inoperative position andbeing so connected that the movement thereof will be controlled by alever adjacent the operators seat.

A still further object of this invention resides in the production of adevice of the kind above described that is simple in construction,efiicient in operation and consists of the minimum number of parts.

With these and other objects in View, this invention consists of certainnovel constructions, combinations and arrangement of parts, as will behereinafter fully described and claimed.

In the accompanying drawings:

Figure l is a plan view of a pair of wheels, the axle casing and theimproved device mounted thereon.

Fig. 2 is a fragmentary view in elevation of a portion of a wheelequipped with this improved device.

Fig. 3 is a vertical sectional view taken through the disk housing usedwith this invention having a disk mounted therein.

Fig. 4.- is a section taken on line 44 of Fig.2.

Referring to the parts by reference numerals, the axle casing isdesignated by the numeral 10 and the wheels in their entirety by thenumeral 11. On the folly of the wheel is provided a supporting ring 12the same having at uniformly spaced intervals thereon the projections 13through which the means 14 is passed to rigidly engage the same with thefelly of the wheel. It is to Speciflcationof Letters Patent.

having passed theret-hroug-h a rod 16 that terminates iii-one end with atappedhead 17 into which is threaded the ground engaging element 18.vIt, is. to be noted thatthis ground engaging element 18 is preferablythreaded into the tapped head 17 so that when. worn it. canbe replaced.

A second bracket is adapted to be secured in alinement witheach of thebrackets'l5, preferably'on the hub of the wheel the said brackets beingdesignated by the numeral 19. On the rod 16 is a coil spring 20 the samebeing in abutment with the plate 21 that is secured on the rod by meansof the pin 22 and at the opposite end thereof from that of itsengagement with the plate 21, the same is in engagement with the slidingsleeve 23 which has its movement on the rod 16 limited by the adjustablecollar 24. Having described that portion of my invention that isattached to the Wheel it is to be noted that although I have onlydescribed one of the members that a plurality of the .same are providedwith each wheel preferably spaced between the spokes of the wheel. Iwill now proceed to describe the operating means of the device above setforth.

Adjacent each of the wheels is provided a disk casing 25 that hassecured therein a disk 26 whichhas at uniformly spaced intervalsthereon, pairs of ears 27 which pivotally connect the strips 28 with thedisk 26. It is to be observed that these strips 28 are pivotallyconnected with the sliding sleeve 23 as at 29. It is to be observed thatthe casing 25 is provided with an overhanging flange 30 to retain thestrips 26 in the same. Each of the housings 25 is provided with areduced collar 31, the same being of such size as toreceive the axlecasing and having connected therewith the connecting strips 32 that havetheir opposite ends in connection with the sliding sleeves 33. A togglecomposed of the arms 34 is connected with the sleeves 33 and anoperating rod 35 is pivotally secured to the arms 34 at their pivotalconnection with each other. A suitable bearing 36 is secured on theaxlecasing for the rod 35.

Patented Nov. 19, 1918. I Applicationfiled Augustfio, 1916. Serial No.117,723.v Q i It is to be understood that when the rod 35 is movedforwardly the disk casings 25 are moved outwardly relatively to the rod35 and the rods 16 are moved outwardly from the hub of the wheel towhich they are attached and the ground engaging elements 18 beyond thetread of the tire.

It is obvious that minor changes may be made in the form andconstruction of this invention Without departing from the material partsthereof. It is therefore not Wished to confine the invention to theexact form herein shown and described, ,but it is Wished to include allsuch as properly come within the scope claimed.

I claim:

'The combination with a Wheel having a ring secured to the fellythereof, of an antiskidding means for said Wheel comprising a bracket onsaid ring,a rod slidab-le through said bracket, a ground engagingelement on the end thereof, a spring on said rod having one end thereofsecured from movement, a

In testimony whereof I afiix my signature in presence of two Witnesses.
